| Abstract: | A method of the atomic-emission spectrum analysis of soil has been developed for control of the accumulation of technogenic impurities in environmental objects. A sample, after calcination at 550°C, is evaporated in an arc discharge. Spectra are recorded by a DFS-8 spectrograph. Simultaneously, determination is made of Li, Ba, Sr, Cu, Zn, Cr, Ni, Co, Pb, Bi, Mo, V, Ge, Ga, Y, Nb, Sn, Cd. For the majority of the elements the detection limits are lower than their percent abundance in the crust and their maximum permissible concentrations.
